first - get as much experience as you can inside a center or two. work the desk, the back, the office, the restaurant, the bar. Learn the business inside and out.
figure out what business model you want to follow - the league bowler model, or the open play/birthday party model. do a LOT of research. Determine a plan, and stick with it. Look outside the bowling business for support.
when you get ready to actually build the center, whatever you do, try to NOT buy new.
Look around for a big building - check out the bowling business demographics for your area, ie. how many people does it take to support one lane.
Look online and try to find some used lanes. A year or so ago, I found 12 complete lanes - wood, no less - for sale, with pin setters, scorers, seating, ball racks, even house balls for $2500 plus shipping. Yes, the shipping is expensive. But the $2500? Just about free...
Find good people that you want to have as partners. Find a good attorney (yeah, I know - an oxymoron) - you'll need the attorney as a key player in your business until everything is set up.
Good luck - and most importantly - FOLLOW YOUR DREAM!!!
